Cool photos that have bikes in them

This photo is from book "Scottish bicycles & tricycles" by Alastair Dodds.

Here's a couple of questions I'd like answers to:

1. Is the boneshaker person a proto-hipster or just a regular dandy?
   
2. Is the anti-social-face kid with a big stick gonna beat the hipster up?
   
3. WTF up with the owls. This fucking isn't Hogwarts.
   
4. Why the kid in the front row has white fake Abe Lincoln beard? Is the hipster's Abe beard fake also?
   
5. Was there fake Adidas in 1869?
